Nilles ABSTRACT: A bucket-type seat for tractors, earth-working vehicles, or the like, in which the seat and backrest are formed as an integral member, and having a pocket or recess adjacent the juncture between the seat and backrest portion and further, having opening means of considerable size in said recess. The integrally formed bucket seat has its seat, backrest and sides all inclined downwardly so as to drain into the seat recess and opening, and the position and construction of the recess is such that good ventilation is provided through the underside of the seat, even though the operator is occupying the seat.

P'ATENTED niczalen INVENTOR RICHARD F: SWENSON W ATTORNEY BUCKET-TYPE SEAT HAVING DRAIN AND VENTILA'I'ING MEANS BACKGROUND OF THE INVENTION Bucket seats for tractors and the like and formed with integral seats and backrests are well known. It has also been suggested to provide a drain for the seat so that any rain, for example, can drain from the seat to facilitate rapid drying before its subsequent use. Such a construction is shown in US. Pat. No. 2,551,819 to Wing, issued May 8, 195], and entitled Cushion Seat Drain Structure. However, that prior art device showed a drain construction which did not completely drain the seat and furthermore could not provide ventilation to the operator while in use. Other prior art devices have made the seat and backrest in two sections, but such construction could not use the benefits of an integrally formed seat.

These and other objects will appear as the description is read in connection with the accompanying drawings.

THE DRAWINGS FIG. 1 is a perspective view of a bucket type seat embodying the present invention;

FIG. 2 is an elevational view, partially in section, and on an enlarged scale, of the seat shown in FIG. 1;

FIG. 3 is an enlarged, fragmentary view of a portion of the device shown in FIG. 2 and showing the drain opening; and

FIG. 4 is a sectional view through the recess and drain opening and taken generally along the line 4-4 of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT The tractor seat S includes a horizontal seating portion 1 and a bucket portion 2 formed integrally as a single unit. The seat includes an interior material such as flexible foam 3 which is covered with a sheet of flexible, waterproof material 4, such as a vinyl-coated material, over its upper inside surfaces. A bucket-shape metal bucket 5 is provided for the seat portion 1 and backrest portion 2 and the material 4 is connected around the periphery of the seat to the edge of the metal bucket 5 by means of an edging 6 in the known manner.

As viewed in FIG. 2, the uppermost surface 7 of the seat is inclined rearwardly in a downwardly direction and the seat also includes sidewalls 8 and 9 which are also inclined inwardly and downwardly. The backrest 2 has an inner side 10 which also inclines downwardly andinwardly of the seat. Adjacent the juncture of the seat portion 1 and backrest 2 is a downwardly extending recess 12 which is formed by the rear wall R3 of the seat 1, a depressed portion 14 of the backrest 2 and two sides 8 and 9 of the seat.

As viewed in FIG. 4, it will be noted that the downwardly extending recess 12 is of considerable length across the seat, and is formedat the juncture of the seat and the backrest. Along the bottom of the recess for a substantial portion of its length is an elongated opening 18 and an elongated metal grommet 20 defines the edge of the opening 18 and acts to seal the adjoining edges of the material 4 together to form a leakproof joint. The recess extends downwardly from the upper surface 7 of the seat for substantially the entire thickness of the seat portion. This provides a deep recess so that when the operator occupies the seat, even though the seat is compressed somewhat, the recess is not closed by the operators body.

The recess and elongated opening 18 act to receive any moisture from the surfaces that are inclined toward it, namely, the surfaces 7, 8, 9 and 10. In other words, all of the upper exposed surfaces are inclined toward the recess and completely drain the seat. Additionally, the opening 18 and recess I2 ensure that good air circulation can be provided upwardly along the back of the operator and into the upper surface in general regardless of the fact that the operator may be occupying the seat.

The present invention provides a bucket-type seat in which the seat portion, backrest portion, and sides are all integrally formed to provide ultimate comfort for the operator as well as an economically produced seat. Furthermore, complete drainage of all upper. surfaces of the seat is provided while at the same time ventilation to the operator's body is assured.

I claim:

I. A bucket-type seat comprising a seat portion, a backrest portion and two side portions all integrally formed as a single unit, an elongated recess formed transversely across the seat and adjacent the juncture of the seat portion and the backrest portion, a transversely elongated opening in the bottom of said recess; the seat portion, the backrest portion, and the side portions all having upper surfaces which are inclined downwardly towards the recess and opening whereby complete draining of moisture from said surfaces through said recess and through said opening is assured and whereby air can pass upwardly through said opening and said recess and generally behind the body of the operator when the operator is normally seated.

2. A bucket-type seat comprising a seat portion, a backrest portion and two side portions all integrally formed as a single unit, an elongated recess formed transversely across the seat and adjacent the juncture of the seat portion and the backrest portion, said recess extending downwardly from the upper surface of said seat portion for substantially the entire thickness of said seat portion; an elongated opening in an extending through the bottom of said recess; the seat portion, the backrest portion, and the side portions all having upper surfaces which are inclined downwardly towards and merging with the recess for complete draining of moisture from said surfaces through said recess and opening, and whereby air can pass upwardly through said opening and said recess generally behind the body of the operator when the operator is normally seated.

3. The bucket seat claimed in claim 2 further characterized in that said seat portion is formed of resilient material covered with a sheet of flexible, waterproof material and is compressible to some extent when occupied.
